Perhaps I am missing something here, Ray, but I wonder if you should really be trying to match frequency responses, or even SPL? The whole idea behind this exercise is to compare the native differences between sealed and ported in your room. And, I think it is much more a listening exercise than a measurement exercise.
To review what brought you to the purpose of making the comparison: you achieved a really excellent frequency response with dual Submersives and some expert assistance. But, as good as the FR was, you felt that there was something missing. Some quality of tactility or excitement that your memory told you that your previous ported sub provided. You described it as "impact". As I see it, part of what you are trying to discover here is whether that quality really exists in ported subs, and whether you really prefer it. And, you won't discover that from measurements of any kind. You will only discover it by pushing the Cap 1400 fairly hard and listening to find out what it's got.
So, I would recommend putting REW away now, and just concentrating on the Cap 1400 for a couple of days. Put it where it measured the best, run Audyssey, since that's how you will be listening to it and since you want to hear it at it's best, and then just play with the LFA and sub boost to discover the full capabilities of the 1400 and your reaction to those capabilities. You can always come back to the Submersive for another comparison in a few days, and it's possible that Mark might even give you another couple of days to compare them, if you are still undecided.
But, the whole point of this exercise is not to discover the ways in which the subs are equal (with level-matching for instance). The point is to discover the ways in which they are not, and whether your memory of the greater "impact" of a ported sub is correct. To do that, you will have to push the ported sub with however much boost you like, at the listening level you prefer. The 1400 should be capable of more SPL in that frequency range that Can and I have been talking about. So, run Audyssey, watch some exciting movies, and play with the sub boost to discover what it's got, and whether it provides the impact you thought you were missing with sealed subs.
I think that's what you need to be doing now. Not measuring and comparing measurements of the two subs.
